An Alaska Native man pleaded not guilty to charges that he murdered two state troopers in the village of Tanana.

Authorities say Nathanial Kangas, 20, shot and killed Sgt. Patrick “Scott” Johnson and Gabriel “Gabe” Rich while they were trying to arrest his father on May 1.
He pleaded not guilty to two counts each of first- and second-degree murder and single counts of assault and evidence tampering.

The father, Arvin Kangas, 58, pleaded not guilty to charges of evidence tampering and hindering prosecution. Authorities say the troopers were called to the village because he had a public safety officer on the night before the fatal shooting.

The Tanana Tribal Council is moving to banish the men forever from the village.
